`which I have filed an application in England, No. 3631, Feb. 9, 1920,) ofkwhich the following is a specification.

This invention'has reference to wheels for self propelled and like vehicles, in which the connection between the hub portion and the felly or rim consists of thin metal disks.

The felly of the wheel willl preferably be of wood or the like, and is held between the outer portions of the disks of the wheel, the

. edges of which project beyond the felly, and

are turned inward to form the holding-in il anges ofthe wheel for the tire or tire cover; and within these parts is a V-shaped groove or recess in the periphery of the vfelly, and` having upon it at the center, in the general plane of the ring, an outwardly projecting rib with a rounded edge, which,when the ring is fitted inthe wheel, will be of greater diameter than the extreme diameter of the disks. Between the base of the rib of the ring, and the flanges of the disks, the beads of the tire cover will lie, and the rib keeps and holds the beads inposition in the flanges.

The-'V-shaped ring may be made of canvas andi rubber, either in laminae or disintegrated `form, or any compound comprising rubber ory other composition or substance, which as a whole in the completed article should be slightly compressible` or soft.

When the tire is in position on the-wheel, the inner tube would `lie over the annular rib of the V-ring; and in the case of the tire being punctured and collapsing, this rib will hold the tire oil?4 the flanges of the disks when running on the road, and so protectdt against injury. I

The invention is'shown in the accompanying drawings, in which Fi ure 1 is a vertical section of the wheel, F1 2 a side View, and Fig. 3 a cross section s owing parts of the wheel in detail to an enlarged scale.

Referring now to the drawings, 1 is the hub of the wheel, 2 is the felly, and 3 the two metaldisks extendin between, and connecting together, the hug and' the felly.

In the casev shown, the wheel is of the divisible kind, and the elly is made in two halves, and the inner disk of the wheel is secured tothe hub; and thecentral the other disk fits over the end of tllrlilll as shown, and is held in position by the screwed cap nut 4; while at the periphery of the wheel, the two parts of the felly 2 and the d1sks 3 are held together by through bolts 5, and cap nuts 6. Y

T he outer edges of thedisks 3 as shown project beyond the felly 2, and are turned 1nward at 7, to form the flanges to engage the beads of the edges of the tire cover 8.

10 1s a V-shaped ring'which lies in a correspondlng `V-shaped groove in the outer edge of the felly 2,.and 11 isfthnJ outwardly projecting rounded rib on the center of the ring 10 which serves the purposes hereinabove described.

By this construction, when it is desired to remove the tire'and replace it, the bolts and .nuts 5, 6, are undone, andthe outer disk 3 with its half felly can be withdrawn bodily away; and then after the tire is in position the outer disk 3 is placed on the side of the other so that the `bolt holes over the bolts 5 register; and then by screwing on the nuts 6, the two parts are drawn up together, and theedges of the tire cover are pressed into position in the spaces or grooves between the disk flanges 7, and the rib 11 of the V- ring 10.

. Referringto the detail shown in Fig. 3, this illustrates the inflation valve tube, which isconnected with the inner tube 12 of the tire; and where this tube comes, the inwardly projecting ledge or rim 11 is partly cut away, and the head 14 of the tube 15 lies in this gap on the inside of the ring as shown. At the point where the' tube 15 comes, thelouter disk 3 ,is slit radially, and also circularly at a point within the flange 7; and this slit part is bent inward as shown in Fig. 3 to the angle of the V-ring 10, and the nut 15X of the valve tube is screwed on the tubeup 7to this part of the disk. The

wood or like felly at this point is cut away as shown.

In this detail the ring 10 is shown in- .closed within an outer wrapping 16 of any lsuitable material'.

The felly portion 2 may be secured to the i `outer-.portions of the disks 3 by screws 17 as shown in Fig. 3.

In cases where the flanges or edgesof the disks 3 are not inturned, and of the ln'nd adapted to mechanically hook the beads of the tire, they will be made of ashape suitable to the edges ot the tire cover used, which tit in them.

The hub in the case ot a detachable wheel, may be a shell hub, as shown in the drawing, adapted to be fitted over the hub poi'- tion carried by the axle, such as are used in connection with detachable wheels ot ditterent kinds.

1t desired in some cases a metal rim or projection may be tormed on or attached to the inside ot the outer disk (or the inner, or both) which comes on the inner edge ot the telly, so as to term a direct support trom the disks on the inside; and also in the case ot the telly being ot wood, tubular distance pieces may be provided through the wood tellies, through which the tastening bolts would pass, so that when the bolts were drawn up tight, the two adjacent ends ot the tubes would come in 'contact with each other.

In the case shown in the drawings, the

' two parts ot the divisible wheel are held together by bolts 5 and nuts 6; but in addition to these, there may be used a tew relatively long bolts and nuts, having ordinary nuts, which would serve to draw the two parts ot the wheel toward one another when replacing the outer part, atter having been opened, and atter this the cap nuts are fitted and screwed over the holding bolts.

`What is claimed is l. A disk wheel comprising a hub portion, an inner disk secured thereto, an outer disk, a hub cap adapted to secure the outer disk to the hub portion, a. telly tormed in annular halves, one halt secured to each disk and adapted to it between the disks when in assembled relation, the outer pe ripheral portion ot the disks extending beyond the telly and tormed into a clencher bead adapted to receive a tire, and a rib carried by the telly and adapted to project beyond the peripheral line ot the disks.

2. A disk wheel comprising a hub member, an inner disk and an Aouter disk secured to the hub member, a telly secured between the disks, the outer peripheral portion ot the disks extending beyond the telly and tormed to receive a tire, the outer periphery ot the telly being tormed with a groove, and an annular member mounted therein and projecting beyond the periphery ot the disks.

3. A disk wheel Acomprising a hub member, a pair ot disks secured thereto, a telly secured between the disks and tormed with a groove in the periphery thereot, the disks projecting beyond the periphery ot the telly and tormed tor receiving a tire, a ring titting in the groove in the telly and extending `inner disk, telly,

Leest/aa beyond the disks adapted to maintain a tire in engagement with the projecting portions ot the disks.

e. A disk wheel comprising a hub member, an inner disk secured thereto, an outer disk removably secured to said hub member, a telly secured between the disks and tormed with a groove, the disks extending beyond the telly and tormed into a tire receiving portion, and a tire retaining ring adapted to tit in the groove in said telly.

A disk wheel comprising a hub member, an inner dat disk secured thereto, an outer conical-shaped disk removably secured to said hub member, a telly tormed in annular halves, one halt secured to each-disk and tormed to provide a groove in the periphery thereot, means extending through the telly tor securing the disks together, the outer edge ot the telly and tormed into a tire receiving portion, and a resilient ring adapted to fit in the groove in the telly and having the periphery projecting beyond the disks.

6. A disk wheel comprising a hub member, an inner disk secured thereto, an outer disk removably secured thereto, a telly tormed in annular halves having one-halt secured to each disk, means extending through the telly and disks tor securing the disks and telly together, the telly being tormed with a groove in its periphery, the disks projecting beyond the telly to provide a tire receivingV portion, and a resilient ring adapted to tit in the groove in said telly and tormed with a rib projecting beyond the periphery ot the disks.

7. A disk wheel comprising a hub member, an inner disk secured thereto, an outer disk removably secured thereto, a telly tormed in halves having one-halt secured to each disk, Ameans extending through the telly and disks tor securing said parts together, the -tellyy being tormed with a V- shaped groove in its periphery, the disks having tire receiving portions projecting beyond the telly, and a V-shaped ring adapted to tit in said V-shaped groove and projecting beyond the periphery ot the disks, said and ring being provided with cutaway portions, and a bore adapted to accommo te a valve stem.
